Based on a rock slope blasting project in a scenic spot, a relevant blasting design scheme is proposed for solving the harmful effects caused by controlled blasting of rock slope in complex urban environment. Weak loose directional controlled blasting was combined with shallow-hole urban blasting and pre-splitting blasting in this scheme. The blasting design parameters of each design are presented with corresponding detonating circuit and sequence as well as charge structure. Through the strict implementation of this scheme, the vibration damage by blasting is greatly reduced and the actual blasting construction effects meet the desired objectives. This design can be reference for similar projects.
